The OP seems rather ludicrous.
What’s the definition of “most speakers”? Many/most audiophiles distinguish differences between high-end audio gear vs box store main stream products which garner the vast majority of speaker sales. So are we comparing current vs 20yrs past consumer box store speakers? What’s the point? Why bring up on this high-end forum?
Consumer box store speakers have to keep costs low in order to compete in a very crowded market. If costs go up, then either profit margins suffer or have to pass on the cost by raising the price which may price them out of the market. Therefore, R&D including material science expenditures are kept low. With limited R&D you’d expect limited results, not sure what the OP was trying to say/prove.
What “measured performance“ data for 20yr old speakers is available for comparison to current speakers? For “most speakers” ~ box store speakers, you’re lucky to find any specifications and if you find any, the specifications are simplistic/rudimentarily unlike high-end components. What’s the point of comparing simplistic/rudimentarily specifications?
Why bring up the subject of “most speakers” on this forum? I surmise that most/all on this forum are audiophiles interested in better content and/or better audio chain performance. We could care less for average box store components comparisons, rather, we’re after a deeper connection to the music often through better components.
